Scion FR-S Rear Side Panel Speaker Size
The Scion FR-S rear side panel accommodates a 4 inch speaker size across all listed model years. Midrange units represent the compatible audio system replacement types for the location. The specifications cover the years 2013 to 2016.
| Year | Type | Size (inch) |
|---|---|---|
| 2016 | Midrange | 4 |
| 2015 | Midrange | 4 |
| 2014 | Midrange | 4 |
| 2013 | Midrange | 4 |
Speaker Types
| Type | Description |
|---|---|
| Midrange | A driver for the middle of the audible range, typically from about 300 Hz to 5,000 Hz, where vocals and most instruments sit. It is often paired with a tweeter and a woofer. |
Additional Notes
- The rear side panel location in the Scion FR-S accommodates a 4-inch speaker across the 2013 through 2016 model years.
- A 4-inch driver occupies a relatively compact mounting footprint, which is consistent with the constrained enclosure volumes typical of rear side panel cavities in sport coupes.
- The rear side panel position places speakers along the lower lateral walls of the cabin interior, angling audio dispersion toward the passenger compartment rather than directly forward or rearward.
- At a 4-inch diameter, the cone surface area limits low-frequency excursion capability, positioning the driver's effective output range primarily in the midband frequencies, roughly between 300 Hz and 5 kHz.
- The Scion FR-S rear side panel location lists midrange as the sole compatible speaker type across all specified model years.
- Midrange drivers are designed to reproduce the portion of the frequency spectrum most associated with vocal clarity and the presence region of instruments, making rear side panel placement in this vehicle relevant to ambient fill and spatial width in the listening environment.
- A 4-inch midrange in a rear side panel position contributes to the mid-frequency layer of a multi-speaker system without the excursion demands that would require a larger woofer cone.
- The mounting depth available in a rear side panel cavity is typically shallower than in door or deck locations, and a 4-inch midrange driver generally carries a shallow-to-moderate mounting depth profile compatible with such constraints.
- Because midrange drivers do not reproduce deep bass frequencies, the rear side panel installation in the FR-S does not require substantial acoustic isolation or ported enclosure geometry behind the mounting surface.
